GAGE MECHANISM FOR PAPER-PERFORATORS.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed July 5, 1913. Serial No. 777,403.

To all whom it may concern Be it known that I, SAMUEL E. HILLns, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Gage Mechanism for Paper-Perforators, of which the following specification is a full disclosure.

My invention relates to a paper perforator having a plural number of movable perforator members supported in relative alinement and definitely spaced from each other, combined. with gage mechanism adapted to be inserted through an aperture in the paper for gaging the paper relatively to the perforator members, so that the multiple series of perforations can be made, all in relative alinement and spacing.

An object, therefore, of my invention is to provide an adjustable gage element of the perforating machine having an indicator point adapted to project through an aperture in the paper to be perforated, to gage the same relatively to the perforator mechanism, together with means for definitely locating and locking the same.

Another object of my invention is to provide an adjustable gage for perforato-r mechanism notched to provide definite adjusting points, adapted to be engaged by locking mechanism releasable by a rotary movement of the gage element.

The features of my invention will be more fully set forth in the description of the accompanying drawings, and other objects will be in part obvious therefrom, the drawings depicting a preferred form of this disclosure and in which like characters of reference denote corresponding parts throughout all the views of which Figure 1 is a perspective view of the device. Fig. 2 is an end elevation, with portions thereof shown in section for clearer observation of the internal mechanism. Fig. 3 is a horizontal mutilated section through the upper portion of the device.

The mechanism for operating the movable perforator members is substantially the same as that disclosed in a prior application to Chesley Dom, filed Dec. 30, 1911, Serial No. 668,767, for paper perforator. It is obvious, however, that the invention herein is applicable to the various types of perforating mechanism known in the art, other than the preferred form disclosed, and that the gaging mechanism may function equally as advantageously for the various classes of perforating machine other than those for perforating paper.

The primary purpose of this invention is to perforate sheets of paper for temporary binders or covers, having a series of binder elements relatively spaced. The number of binder elements of the various types of binders vary according to the size of the binder and also as to their serial groups, and to avoid the manufacture of a special perforator to meet each condition of the market, I accomplish the result by providing a limited number of perforator members combined with the gaging mechanism adjustable to different definite locations relative to the perforator members so that a greater series of perforations can be made in longitudinal alinement and predetermined relative spacing than the number of perforator members. This materially reduces the cost of the punching device, en-

larging its scope of use, and adapts it for various sizes of temporary binding devices to meet the conditions of the trade.

The base 1, and the punch member supporting head 2 are of integral construction in the preferred form, although it is obvious that the head 2 may be adjustable upon the base as shown and described in the aforesaid application.

3 represents a slot out horizontally into the head 2, to provide a paper receiving throat between the punch members, withthe die element 4: of the punch formed integral therewith, although a removable die plate may provided.

5 represents a movable punch member, and in the drawings a series of three are shown, all duplicates of each other and relatively spaced from each other. Each are provided with rack teeth 6, adapted to intermesh with a rock shaft 7, common to all and journaled within the head 2, its ends projecting beyond the same and to which is fixed a handle 8 for reciprocating the movable punch members 5 in unison. While I have shown three punch members in a series, it is obvious that the number may be varied, although three offer a combination most adaptable for these specific purposes herein referred to.

I have provided two gaging devices, one for the marginal edge of the paper to be perforated, and a second for gaging the perforations of one series relatively with a second series to be made. The paper gaging device is substantially the same as that shown and described in the aforesaid application comprising an angled rod 9 slidably mounted in the horizontal bore 10 formed in the head 2 and secured in any adjusted position by means of the screw 11 engaged through the head 2, as shown in Fig. 3. This gage is shown in the left of the device, moving over the table extension 12; the upper surface of the table being in a plane with the base line of the throat 3. The perforation gage comprises an angled rod 13 movable within the bore 14:, formed in the head 2.

The end 15 of the rod projects upwardly 1 and is provided with a stud 16, of similar The rod is provided with a series of" notches 17 adapted to be selectively engaged with the spring actuated detent 18, movable within a bore formed in the head, (see Fig. 3). A spring 19 in rear of the detent exerts a forward pressure thereto for automatically engaging the detent within a notch in the rod 18. The spring is maintained within the bore and its tension adjusted by a screw 20, screw threaded into the bore. The rod is released for adjustment by a slight turn sufficient to depress the detent, whenever it is moved longitudinally and rocked to a normal notch and detent alining plane for the detent to automatically engage with a second selected notch. The notches are of predetermined spacing to properly locate the gage point 16 the desired distance from the punch members.

It will be seen that the sheet 21 (shown in dotted lines, Fig. 3) has one series of three perforations, one perforation fitting the gage point 16, thereby properly positioning the sheet for the second punching so as to relatively space all of the perforations. If a sheet is to be perforated to fit, say a binder member having five binding elements, the sheet would first be perforated with three perforations after which it would be moved to bring its first perforation in registry with the gage point 16, which would present the third perforation in registry with the first punch member of the series, for making the remaining perforations required to com plete the number. Thus it will be seen that after one perforating operation the paper can be positioned for successive operations for making a longitudinal line of perforations of definite relative spacing from a limited number of punch members.

Having described my invention, 1 claim A device of the nature disclosed combining a frame structure, a gage member projecting from said frame structure having a stud and shouldered end as a support beyond said frame structure adjustable to measured distances therefrom, and means for clamping said rod in its adjusted positions, said rod releasable therefrom by a partial rotation.

In witness whereof, I hereuntosubscribe my name, as attested by the two subscribing witnesses.
